Joss Whedon was a guest on “Late Night with Jimmy Fallon” last night and Fallon tried to get a scoop out of the filmmaker about Marvel’s The Avengers 2.

He asked whether there are new characters and Whedon replied, “There are new characters. I’ve already said that we’re going to have a brother-sister team, the Scarlet Witch and Quicksilver, who were great mainstays of The Avengers when I was reading the comics as a kid.”

Fallon said that he did not know the characters and then asked whether they had started casting them yet. Whedon said, “Not yet, we’re doing that now.”

Whedon said he is writing the sequel now and then was asked why he picked the two characters. He said, “well, besides the fact that I grew up reading them, their powers are very visually interesting. One of the problems I had on the first one was, everybody basically had punchy powers. ‘I can hit,’ ‘I can also hit.’ Hopefully it didn’t get too boring. But coming into the second one, he’s got super speed. She can weave spells and a little telekinesis, get inside your head. There’s good stuff that they can do that will help sort of keep it fresh.”
